When Syntax Errors Cause Nightmares

The problem with network upgrades is that we usually have an idea of what a successful upgrade implies in our head and we base our testing on it. Needed better connectivity and managment of the routers linking two sites, and all went well. Internet access was confirmed, upgraded speed was confirmed and all services exposed work.

Vyos Script to Update DDNS Peers

Vyos seems like a great project but it’s documentation gives you an odd feeling as if you are looking at Lorem Ipsum stances. According to T4930 it’s supposed to support dynamic dns for wireguard peers but sadly it still doesn’t. So here we are, this script goes through a given list of peers and updates the config.

This is the Ansible template I am presently using to deploy the NGINX configuration file

Headscale NGINX Reverse Proxy Configuration

Spent some time to get HAProxy to work with Headscale to no avail, so decided to use NGINX which never fails to disappoint. This is a verbatim copy of the Jinja2 template I use in Ansible, but just replace the items in {{ }} with your values.

Ansible get_url with regex to fetch the latest github release from a repo

This is the best I’ve come up with so far to get_url within Ansible to fetch the latest release from a Github repository. To customize to your needs, change the url portion to point to your desired repo (this one points to Duplicacy) and then adjust the “linux_x64” to a substring from the release files to narrow down what file you want.
